Those are two different species of Hibiscus, Lynn, so that one isn't a duplicate.
The Brassica entries can't be duplicates. One is a cabbage and the other is broccoli.
There are two different cultivars of Narcissus named 'Horizon.' There's usually a comment by jmorth to say so, and there is one on the page for the second 'Horizon,' but I suppose he should have added a pertinent comment to the first entry as well.
I don't know about the lilies. Check with the monitor for that section of the database.
